Arrange for a candle light dinner in a restaurant keep romantic music playing in the background. After you finish your dinner ask the waiter to bring a tray decorated with petals and a jewelry box in the center attached with a card expressing your feelings. The most amazing one can be when you take your partner to an echo point shout your proposal on the top of your voice and see the words coming back to him/her several times. If your partner likes pet, do something fascinating like buying a talking parrot and teaching him how to speak and say "I love you"
If you have the keys of his/her house, decorate it with flowers and other things of your choice. When your partner comes be near the door to give a warm welcome and propose with a ring in your hand.
